without prey; a Syrphid, Helophilus sp., near to but not identical 
with africanus, Yerrall; lastly, something extremely like Musccl 
domestica. 
As might have been expected Dragon-flies were fairly numerous, 
prominent amongst them the large and handsome Pseudo-macromia 
torrida flying in the open swampy space between the belt of Eugenia 
trees and the edge of the chasm ; other species were Phyllomacromia 
trifasciata, Ramb., and (by sweeping) the Demoiselle, Brachybasis 
rhomhoidalis, Reauv., which appears to have a wide distribution in 
Africa. 
Two Wasps were taken, Eumenes tinctor, Chrst., and Ammophila 
beniniensis, both females, while sweeping produced an Ichneumon-fly. 
Ants were represented by a solitary Camponotus sp., of which Colonel 
C. T. Bingham wrote, “ Hew, but as a single specimen I cannot 
venture to describe it; allied to C. sericeus, Fabr.” 
The Orthoptera if not numerous were variously represented by a 
Mantis larva obtained by sweeping; four Cockroaches of the genus 
Ischnoptera , sp. nov. (near to bimaculata , Gerst.), found under stones 
and running very rapidly away when disturbed; Mr. Shelford has 
been good enough to describe this as I. longstaffi. [Plate II., Fig. 11.] 
Sweeping yielded also many Grasshoppers, one of which had its head 
and thorax conspicuously marked by two lateral yellow stripes. 
Prototettix impressus , Stal, was taken on a tree. 
When looking for beetles two very active little Bugs were found 
under stones or leaves, another was adorned with a red abdomen. 
Sweeping as usual yielded sundry Homoptera. The same operation 
produced a few Beetles: a Lagria ) in the collection at South 
Kensington, but unnamed, of which five specimens were obtained; 
a single Cryptocephalus callias , Suff.; two of the Phytophagid Lema 
chalcoptera, Lac.; six Haltica indigacea , Illig.; two Hispa sp.; also 
one II. bellicosa, Guer., of which the National Collection has speci¬ 
mens from the Gold Coast only. Lastly, three Staphylinids, Osorius 
rugiceps , Boh., were found under dead wood. 
In such a spot it was but seemly to find an Amphibian, accord¬ 
ingly we may note that a toad-like Frog was abundant among the 
marshy spray-drenched grass between the Rain Forest and the 
Chasm. Many of them were extremely small, hardly larger than 
blue-bottles. A large specimen evacuated a mass of elytra, etc., of 
small beetles, apparently mostly geodephagous but some perhaps 
phytophagous; this was interesting, in so far as it bore out our 
experience that the Coleoptera of the Forest were very small. 
Three species of Land Snails were found in the Rain Forest; two
